Action 7 News went to the homeowner for some answers about the attack, but no one came to the door.

Other neighbors said there are actually two pit bulls living at the home, and that they both have a history of lashing out at other neighborhood dogs.

I literally had to beat it off with a 2-by-4 four times. It would not let go, its jaws were locked (on my dog), Michelle Dowdle said.

The boys mother said he was in surgery Sunday night at UNM Hospital to repair his arm. She said he was playing at a neighbors home and then the boys somehow ended up in another yard with the pit bull.

Moriarty police said the two pit bulls are now at the citys animal control department. They said the dogs could be euthanized and the owner could face charges.
